 ^^^^^^^^^^^^

 Reformat Paragraph rewraps a block ('paragraph') of contiguous equally
 indented non-blank comments, a similar block of text within a multiline
 string, or a selected subset of either.
 If needed, add a blank line to separate string from code.
 Partial lines in a selection expand to complete lines.
 The resulting lines have the same indent as before
 but have maximum total length of N columns (characters).
 Change the default N of 72 on the Window tab of IDLE Settings.
